DRAW-BAR AND YOKE CONNECTION.

Specification of Letters Patent.

Patented Dec. 3, 1918.

To all whom it may concern:

Be it known that I, CALVIN B. PA'roH, a citizen of the United States. residing at Gle-nellyn, in the county of Dupage and State of Illinois, have invented acertain new and useful Improvementin Draw-Bar and Yoke Connections. of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings. forming a part-of vthis specificatiom This invention relates to improvements in draw bar and yoke connections.

The object of the invention is to provide v simple and effioien't means for detachably connecting a standard draw bar and a yoke strap and which permits the reemployment, without modification, of old yoke straps of the riveted type.

In the drawing forming a part of this specification, Figure 1 is a longitudinal sectional view, broken away, of a draw bar and yoke showing my improvements in connection therewith. Fig. 2 is a view similar to Fig. 1, but illustrating another embodiment of the invention. Fig. 3 is a vertical, transverse. sectional view of the structure illustrated in Fig. 2 and taken on the line 3-3 thereof. Fig. 4 is a sectional View of the lower portion of a draw bar butt and lower arm of ayoke strap illustrating another embodiment of my invention. And Fig. 5-is a view similar to Fig. 4 illustrating a still further embodiment of the invention.

Referring to the construction illustrated in Fig. 1, 1O denotes draw bar having the usual upper and lower front shoulders 11 and 12 and the. usual standardly spaced rivet holes 13-13. The front ends of the arms of the yoke'a're desig nated at 14-14,each of the sams being provided with the usual standardly spaced rivet holes 15-15 alin'ed with the rivet holes of the draw bar butt, and inwardly turned gibs or shoulders 16 that cooperate with the shoulders of the draw bar butt. Y

Surrounding the draw butt and the yoke strap is a rectangular band 17, the same having small perforations 18-;18in its upper wall and perforations 29-29 in its lower wall of the same size asthe perforations or holes provided in the yoke strap and draw bar butt. Extending through the alined holes'or perforations of the lower wall of the band, the yoke arms and into the perfothe butt of a standard 1 rations 18-18 are pins 19-19, each of the latter being reduced at their upper ends as indicated at 19 to fitsaid perforations 18.

The pins 19 are supported in proper position by any suitable means such as cotters 20-20, which pass through suitable holes in the lower portions of said pins and alined holes in a depending lug 21 on the bottom wall of the band. p v i In order to disassemble-the yoke and draw bar, -it is apparent that the cotters 20 are first withdrawn, after which the pins may be dropped down and subsequently the band 17 slipped forwardly to permit the yoke arms to be disengaged from the draw bar. In the event difficulty is experienced in removing the pins 19, the same may be forced out by means of suitable tools inserted through said perforations 18-18.

In the construction illustrated in Figs. 2 and 3, the drawbar and yoke are similar to the corresponding parts of the structure illustrated in Fig. 1 with the standardly spaced rivet holes. In this form, a rectangular band preferably a'casting 117 is employed, the latter being provided in its lower 7 120 that passes through suitable perforations in a pair of depending ears 121-121 formed on the lower side of the band. In this construction also, the band 117 is provided at the top with small perforations 118-118 to facilitate removal of the .pins 119 when necessary to employ a tool to force the latter out.

In the form illustrated in Fig. 4 the ar rangement is similar to that illustrated in Figs. 2 and 3, except that the pins 219-219 are supported by means of a clip 220, the

clip being held in position by a pair of small cotters 22O -220 passing perforations in the depending ears 221-221 formed on the lower side of the band.

In the construction illustrated in Fig. 5, the arrangement of draw bar and yoke is the same as illustrated in the other figures. this form, however, the pins 319-319 are inserted through the alined perforations of the yoke and draw bar before the band 317 is applied. The latter is slipped rearwardly over the butt of the draw bar, the ends of the yoke arms andthe pins after the latter have been assembled. The band 317 is provided at the bottom thereof with a downwardly offset wall 41 which forms a suitable seat or ledge for the lower ends of the pins 319 and thus supports the latter. In order to prevent the band from becoming displaced after the parts are assembled, a cotter 320 is employed which extends transversely of the band and is located so asto engage the rear side of the rear pin 319.

I claim:

Ina device of the character described, the combination with a draw bar and yoke strap having standardly located rivet receiving 'holes, of a plurality of pins extending through said holes, a band encircling the draw bar butt and the ends of the yoke strap, said band having a top wall engaged by the upper ends of said pins to thereby i.

limit the upward movement thereof, the lower ends of said pins projecting below the lower arm of the yoke strap, the bottom of said band being formed to accommodate said projecting portions of the pins, and detachable means associated with the bottom por- CALVIN B. PATCH.
